This volume includes essays presented at the conference on Emotions and Rationality in Moral Philosophy held at the Universities of Neuchâtel and Bern in October 2005. The authors of this volume share the Humean insight that the ‘sentiments' have a crucial role to play in elucidating the practice of morality. In a Humean fashion, they warn us against taking an intellectualist view of emotions and reject the rationalist account of morality. In contrast to Hume, however, or at least in contrast to some interpretation of Hume's moral philosophy, some contributors to this volume are optimistic with regard to the weight our emotions and emotional dispositions should play in moral theorising.
